INTERRELATION BETWEEN DESIGN AND METHODS OF CONSTRUCTION FOR ELEVATED HIGHWAYS

THE INTERACTION BETWEEN DESIGN AND CONSTRUCTION IS PART OF THE PROCESS OF THE DEVELOPMENT OF NEW CONSTRUCTION FORMS. IF THIS PROCESS IS TO FUNCTION PROPERLY, MORE ATTENTION SHOULD BE PAID TO THE FEEDBACK FROM CONSTRUCTION TO DESIGN. VARIOUS CONSTRUCTION SYSTEMS FOR BRIDGES ARE BRIEFLY DESCRIBED VIZ: ON-THE-GROUND, MOVEABLE SCAFFOLDING. 2) CAST-IN- PLACE SPAN- BY-SPAN CONSTRUCTION WITH THE AID OF SUSPENDED, SELF- LAUNCHING FORMWORK CARRIER. 3) CAST-IN-PLACE SEGMENTAL CANTILEVER CONSTRUCTION. 4) PREFABRICATED BEAMS. 5) PRECAST SEGMENTAL CONSTRUCTION SUPPORTED BY SCAFFOLDING. 6) PRECAST SEGMENTAL CANTILEVER CONSTRUCTION. 7) SELF-LAUNCHING PIECEMEAL SYSTEM (GERMAN "TAKTSCHIEBEVERFAHREN"). IN THE SECTION OF THE STATICALLY DETERMINED SYSTEM, ATTENTION IS PAID TO THE DEVELOPMENT OF A JOINT CONSTRUCTION WHICH WILL NOT INTERRUPT TRAFFIC. THIS CAN HAVE FAVORABLE CONSEQUENCES FOR THOSE SYSTEMS WHICH MAKE USE OF A GREAT NUMBER OF JOINTS. MENTION IS MADE OF SOME SOLUTIONS FOR CONNECTING THE SUPERSTRUCTURE TO CONCENTRATED PIER COLUMNS. THE WRITER IS OF THE OPINION THAT AT PRESENT THERE IS NOT MUCH POINT IN FURTHERING THE DEVELOPMENT OF PRESTRESSING AS FAR AS THE DEVELOPMENT OF BRIDGE CONSTRUCTION IS CONCERNED. /TRRL/
